Anti-Hydro will raise the percentage of hydration of this mix (the amount of cement that actually chemically reacts with the water) from the usual 65% to 70% range to approximately 95%. This is a significant change to the final properties of the product which yields denser, harder material which is impermeable to water and a near total vapor barrier as well.
Anti-Hydro is a high-range accelerator too. This means that the concrete mix will harden far faster than normal and that means when it’s used in winter it will harden before it freezes. And, it allows for far faster installation… more control over your work in less time.
